In fact Lpgc most of your 'idle speculation' appears to have been innacurate .... or did you not actually read her Wiki entry (again) ?!....
Patently not, or your Aspergers comment would not have been made either.... She's simply not your 'standard' 16 year-old-kid....
How many others do you know who have been considered for a Nobel ?
Here's a problem for you though "You May Say/Speculate That She's A Dreamer - But She Is Not The Only One ! "......
I am not going to presume to reply to your further questions/speculations to her either: Send her a note, post the reply up here...
You'll See Lpgc !!
On a more general note however the 'microphone on' remark relates to Politicains hearing .... but not actually listening.....
and kids have (finally) noticed this too... and not just because eco-warriors like her have pointed it out either !
Interesting choice dave3d; Diesel AND Electric; God knows what the 'authorities' will do with that ! Keep us posted on developments
'Common Platorm' build is quite common now of course: If not a rude question why not just get the Volvo version ?
Yes, there are still EV Manufacturers who think (kids) 'pester power' will work as far as hybrid/sales are concerned.....
Did some more research on this, specifically:-
... but it is going to take more that a Smart Phone App. to convince me it is 90K well spent....
Not sure I would really want to drive_ this _through a stream/ford either :-
Back (more) on track:

No need to speculate (negatively/inaccurately) about Greta Lpgc, Just Google her !
And you do know she has Asbergers, right ?
https://en.wikipedia.org/wiki/Greta_Thunberg
And I read this book yesterday: A collection of her speeches:
"Is my microphone on, can you hear me" ?....... indeed
https://www.amazon.co.uk/One-Too-Small-Make-Difference/dp/0141991747
Yes a kid but a Smart Kid ; Watch Out !
And, finally, I would much rather listen to her than our so-called 'leaders' who (far too often) sound like spoilt/stupid kids....
Well Greta did'nt get a Nobel Prize so she, and the millions like her, are free to not 'calm down' either !
And surely we have to admire kids willing to get 'arrested' for their beliefs.....
Maybe The Chinese will be the first to devise Fusion Reactors too; In the meantime they are quite happy to supply the World With PV Cells of course..
and EVs.... and..and.. but Dyson was supposed to be developing a 'solid state battery' but failed so maybe The Chinese will be first with that too** ? .
In the meantime:

As we know Richard our Politicians really are not very good at "thinking things through" .... I suspect some jumped on the EV bandwagon as it provided a solution to the Diesel/NOx mess they caused and thought it would be a 'stimulation' to the Car Industry (and it may well have been if the EVs were not so expensive still and 'suitable ££ encouragements' had continued too....
That said there is a market for EVs but mainy for town travel....(?) HIghways/Motorays less so...(?)
It just that the Chinese will be making most of these cars (apparently) !
Do they still have steam trains up there Harv ? Just joshing but yes there are too many unexploited fossil fuels still in the ground...
In the meantime it looks like Greta Thunberg is heading for a Nobel Prize (?)
Hmmmm....
Maybe Dyson read this thread ?
or this:
https://www.carmagazine.co.uk/electric/how-much-ev-charging-and-running-cost/
Meanwhile.....
https://www.driving.co.uk/news/dyson-confirms-electric-car-will-launched-2020/
but:
Slighty sad, but presumably their marketing people were not prepared to mislead this time ?
Besides, I really wanted to see these on the roads:
" **The main tech innovations in Dyson’s breakthrough EV (now mothballed)
1) Solid-state battery
Although based on lithium-ion tech, the pressurised liquid electrolyte is replaced by a thin layer of non-flammable material that acts as both the separator (keeping positive and negative electrodes from coming into contact) and the electrolyte (allowing ion transfer to happen).
2) Safer than liquid
Lithium-ion batteries typically run at 35°C, demanding complex cooling for EVs, and both Tesla and GM’s batteries have suffered fires. To extend their service life, the batteries should never be fully charged or discharged. Solid-state batteries don’t suffer from these problems.
3) Clever motors
Dyson’s digital ‘switched reluctance’ motors benefit from excellent packaging and mechanical design, says Wilson. They offer good cooling and thermal performance – which is key – while aerodynamically efficient rotors, that are quiet and cool, minimise losses.
4) A question of scale
With brushless motors already 90+% efficient there isn’t a lot of headroom for Dyson’s digital motor. It will have inertia and thermal challenges if scaled up to car size, on top of losses generated by electric fields in the rotor. Using a series of laminations reduces these losses.
** "
Impressed with those tiny Radial engines Bolt (albeit a bit pricey). Also takes me back to my youth (spending days with balsa wood etc to build model aircraft that could get trashed in seconds colliding with a tree..) Lots of R/C planes seem to be going electric though too.... although not because of pollution.
On refllection I think Dyson used the word "digital" because "brushless vaccum' sounds wrong ?!
https://www.youtube.com/watch?v=yajwmhe96pg
-Don't think these particular techniques can be scaled up in order to propel a car though.....
~100k RPM might be good for a model plane however !
Oh no, ICE-pwered vaccum cleaners...... but will I have to pay the ULEV charge to use it in London ??
Looks like you could get wealthy using it though:
https://www.instructables.com/id/A-gas-powered-vacuum-cleaner-for-use-in-gold-prosp/
Been familiar with Digital Motors for a while: The first one I encountered was the Direct Drive Strathern Turntable (1973); This had 'two states' in more ways than one..... notably when started it could turn in either direction (!); Oooopps.... Background for those interested (and some BL info. too) :-
Knock on ? Well they knew adding lead to petrol (because of knocking etc) was a bad (unhealthy) idea for a long time of course....
https://www.bbc.co.uk/news/business-40593353.
... but I suspect the more recent problem was when they started to use ECUs, Hegos etc (as well as the Catalytic Convertors) to remove other pollutants.. Again you will be aware that a push for (standardised) OBD followed (although the Car Manufacturers did not like it that much - of course: How could they (over)charge for Diganostics/repairs then etc etc ? )
Yes, Dyson are just using a gimmick.... it if really were a 'digital' motor it would be off then on then off then on etc ?? Maybe it is, in a way (but I know what you mean). Presumably digital means "magic" to many consumers (whereas I tend to think it just means "unnecessarily complicated / expensive to repair". ? Maybe they will even have a 'digital turbo motor' in their EVs (or some other hype/nonsense) ?!
Ok, I considered this some more and I am (again) leaning towards:
https://www.dyson.co.uk/automotive.html
Any 'UK' company that manufactures abroad, can get folks to buy hair dryers for £300 (when you can get something nearly as good for £30 must be onto something. Hmmm... all thanks to 'digital motors' ? ..... what's next ? Digital batteries.?... "2020" ?? Well I forecast somthing the size of a Smart Car , £50K and purple... and around 2025.....
Realise you are just being a bit provocative there Richard, but, whilst we are bringing back lead, can we also bring back coal too as I am getting nostalgic for smog and steam trains.... and maybe these folks won't notice (?): https://en.wikipedia.org/wiki/California_Air_Resources_Board
As mused numerous times before perhaps the answer was (is ?) for cars to be built to last 20 years.... and don't even get me started on 'scrappage schemes'... Our scrapyards are full of cars only ~10 years old..... aka "beyond econonomic repair".... why, exactly ?
Overall I wonder how many Politicians actually understand how ICE works..... or if they simply just prefer to listen to lobbyists instead ?
Edit: I have decided to cover my roof/garden etc with PV cells - just in case
Maybe I can get a Govt. Grant to pay for this if they are so 'green' now ....?
That's what I said so I don't think an extra 'exactly' helps Richard !
What concerms me is - as we know - just what an easy target motorists are 9which is why I mentioned 'indirect taxation' a few posts back.
The Councils I deal with tell me (eventually..) that Central Government have made such deep cuts now that they' really don't have any alternatives but to make up the shortfall elsewhere'. Bad signage seems to be their main 'tool' in that regard, CCTV being used to monitor those places and then issuing Tickets at £50+/pop. (The cameras are 15K..... and these places often raise £500K/year in fines.... !!)
Overall 'simply' I wish they (Politicians) would be more up-front about their motives/rationale but that's not how they operate of course... as they can, just about see as far as the next General Election, promising The Earth but then delivering a pile of manure.... (and The Kids are onto this like never before)
How crazy is it when an outgoing PM makes some 'statement' about us being 'Carbon Neutral by 2050'.. when she will be in her 90s !
How crazy is it that any of us believe all the 'promises' anyway ? Oh no, I can feel it all coming on now... How Dare They !
Thanks for your detailed explanation about converting Black Cabs Lgpc: Overall then (longer-term) it may well be better for owners to take that paultry £10K grant towards buying an 'Alternative Fuel' vehicle after all (?)
Whilst I can understand the growing NOx problems etc in the bigger cities clearly some other towns are currently (or will be..) using this as a revenue-generator scheme of course, using pollution as their primary excuse....
Ok, so a question aimed (mainly) at Lpgc:
As you will know via LPG conversions London Black Cabs can have their 'lives' extended from the 12 years being proposed back to 15....
Q: Is it worth it ?
https://www.london.gov.uk/press-releases/mayoral/24m-funding-boost-for-black-cabs
All this talk of salt water etc is making me wonder how big a sail I would need to do 50mph..... although the 'tacking' against the wind could be a problem of course.... but at least that could qualify as 'Dual Fuel' then for the ULEV (indirect taxation) charge ??
Anyone got map of London showing routes without low bridges ?
(Just recalled James May and his Triumph)
And the problem wih Hydrogen as fuel is we would have to modify our engines extensively (eg. '50% more expensive') and then only get '50% of the power'..... ? ( https://en.wikipedia.org/wiki/Hydrogen_internal_combustion_engine_vehicle )
Hmmm... then suppose I have a big (folding) sail made of PV Cells instead and an Electric Motor ?......... Err........
Back to Wiki:
https://en.wikipedia.org/wiki/Toyota_Mirai
UPDATE: Lidl are now doing Electric scooters @ £300
Too bad they can't be used (legally) on the road......
So will just sticking a "Hybrid" badge on my P38 cover me for it then ?
Better mention this too, even though (ominously) 'the first one won't be working until 2030':
https://www.fircroft.com/blogs/uk-government-to-invest-pounds18m-in-rolls-royce-smr-programme-92062595352
(but at least they had the sense to change their 'pitch' to 150.000 homes though......?)
Accordingly they have already 'thought this all through' though.........eg. https://www.uknuclearsmr.org/
Fortunately their very-specific "62,857" figure made me think/realise it was an April Fools joke too...
